Abstract

The invention discloses a cutting process of a multi-pole laminated diaphragm, which comprises the following process steps: laminating the bottom diaphragm; pressing the diaphragm; cutting the diaphragm and stacking the poles; stacking the middle diaphragm; pressing the diaphragm; cutting the diaphragm and stacking the poles; Diaphragm cut into slices; top-layer diaphragm stacked; diaphragm cut and pressed; overall transfer; diaphragm layer cut as a whole; CCD re-inspection. The multi-electrode lamination diaphragm cutting device includes a lamination cutting mechanism and a lamination cutting mechanism respectively arranged at the lamination station and the cutting station. The lamination station is also equipped with a platform and a film pressing mechanism. Correspondingly arranged on both sides of the lamination platform; the lamination cutting mechanism is arranged above the lamination platform; the pressing and cutting mechanism is arranged above the platform. The invention adopts diaphragm pressing and synchronous multi-pole sheet lamination, and cuts the diaphragm in parallel. The lamination accuracy is ensured by pressing the diaphragm, and at the same time, the lamination and cutting diaphragm are linked to effectively improve the lamination efficiency, and it has the linkage function of pressing and cutting to ensure the cutting accuracy. While improving the cutting efficiency.

Description

A multi-pole laminated diaphragm cutting process and device technical field The present invention relates to the field of lithium ion batteries, particularly a kind of multi-pole sheet lamination separator in the field of lithium ion power batteries. Film cutting process and device thereof. Background technique As the country vigorously promotes the development of new energy, the demand for lithium-ion power batteries in all walks of life is increasing day by day. In the composition of the ion power battery, the battery cell is its core component, and the battery cell is generally formed by overlapping positive and negative electrode sheets. The composition structure of the battery cell includes a plurality of positive and negative electrode sheets that are staggered and stacked up and down, and the positive and negative electrode sheets are isolated and insulated by a diaphragm.

[0003] At present, the manufacturing process of the electric core includes two ways of s...
